This application is a continuation patent application of U.S. patent application Ser. No. 15/831,222 filed Dec. 4, 2017 and titled “Electronic Device Charging System,” which is a continuation patent application of U.S. Ser. No. 15/086,730, filed Mar. 31, 2016 and titled “Electronic Device Charging System,” now U.S. Pat. No. 9,837,835, which is a continuation patent application of U.S. patent application Ser. No. 14/201,663 filed Mar. 7, 2014 and titled “Electronic Device and Charging Device for Electronic Device,” now U.S. Pat. No. 9,455,582, the disclosures of which are hereby incorporated herein by reference in their entireties.

TECHNICAL FIELD

The disclosure relates generally to electronic devices, and more particularly, to an electronic device, a charging device and a method for charging the battery of the electronic device.

BACKGROUND

Current electronic devices continue to become more prevalent in day-to-day activities. For example, smart phones and tablet computers continue to grow in popularity, and provide everyday personal and business functions to its users. These electronic devices are usually operational for the majority of a typical day, where a user my utilize the electronic device to send messages (text, e-mail, etc.), work on documents, play games, conduct phone calls, and perform other personal and/or business specific tasks.

With extensive daily use, the desire to have a long battery life is one of the most important operational characteristics of the electronic device. However, as the overall size of the electronic device continues to get smaller, the internal space of the electronic device also gets smaller. This reduced internal space may result in a smaller battery as well. With a smaller battery utilized in electronic device, the battery may need to be charged daily, or even several times a day.

The charging of the electronic device typically includes electrically coupling the electronic device to a charging device. The charging device may provide an electrical current to the electronic device, and the electronic device may convert the current to charge the battery. Conventional charging devices for the electronic device may charge a depleted battery to a threshold charge value (e.g., 100%). Once the battery reaches the threshold charge value, the conventional charging device may stop providing an electrical current to the electronic device, which may ultimately allow the maximum charged battery to deplete. When the battery depletes to a predetermined minimum charge value (for example, 90%), the charging device may once again provide electrical current to the electronic device to charge the battery to the threshold charge value again. When an electronic device remains connected to the conventional charging device, the cycle between threshold charge value and predetermined minimum charge value may occur several times.

With each charge to the threshold charge value and/or each cycle between the threshold charge value and the predetermined minimum charge value, the life of certain types of batteries may be reduced. More specifically, each time such batteries cycles between the threshold charge value and predetermined minimum charge value during the conventional charging process, the battery's ability to hold a maximum charge for a duration of time may be substantially reduced. Over time the reduction in the battery's ability to hold the charge may result in the battery needing to be charged several times a day. When the battery cannot be charged several times a day, the battery may be completely depleted and the electronic device may be inoperable (e.g., shutdown due to lack of power).

SUMMARY

Generally, embodiments discussed herein are related to an electronic device, a charging device and a method for charging the battery of the electronic device. The electronic device may include a battery and a charging system for charging the battery. The charging system may be configured to monitor the activities and/or events of the electronic device to ensure that the battery is substantially charged prior to, or immediately after the occurrence of an event. That is, the charging of the battery may be dependent upon the monitoring and/or the occurrence of activities and events of electronic device, and not cycling between threshold charge values and minimum charge values. As a result, the charging system of the electronic device may substantially prevent undesirable depletion of the battery's ability to maintain a charge. That is, by eliminating the cycling charging of the battery of the electronic device, the charging system of the electronic device may minimize and substantially prevent the depletion of the battery's ability to maintain a charge.

Additionally, the charging system may be configured to recharge the battery in response to detecting one of: the anticipated event occurring subsequent to the recharging of the battery, or the unanticipated event occurring immediately before the recharging of the battery.

Another embodiment may include a charging device for an electronic device. The charging device may include a connection portion electrically coupled to a battery of the electronic device, and a charging system in electronic communication with the battery of the electronic device.

The method may also include recharging the battery in response to detecting one of: the anticipated event occurring subsequent to the reactivating of the charging device, or the unanticipated event occurring immediately before the reactivating of the charging device.

It should be understood that the following descriptions are not intended to limit the embodiments to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the appended claims.

The following disclosure relates generally to electronic devices, and more particularly, to a charging device and a method for charging a battery of an electronic device.

In a particular embodiment, the electronic device may include a battery and a charging system for charging the battery. The charging system may be configured to monitor the activities and/or events of the electronic device to ensure that the battery is substantially charged prior to, or immediately after the occurrence of an event. That is, the charging of the battery may be dependent upon the monitoring and/or the occurrence of activities and events of electronic device, and not cycling between threshold charge values and minimum charge values. As a result, the charging system of the electronic device may substantially prevent undesirable depletion of the battery's ability to maintain a charge. By eliminating the cycling charging of the battery of the electronic device, the charging system of the electronic device may minimize and substantially prevent the depletion of the battery's ability to maintain a charge.

The electronic device may include a battery, and a charging system in electronic communication with the battery. The charging system may be configured to charge at least a partially-depleted battery to a threshold charge value, discontinue the charging in response to the battery being charged to the threshold charge value, and monitor the function of the electronic device to detect at least one of an anticipated event, and an unanticipated event of the electronic device. Additionally the charging system may be configured to recharge the battery in response to detecting an anticipated event, occurring subsequent to the recharging of the battery, or an unanticipated event, occurring immediately before the recharging of the battery. Charging device and charging methods are also disclosed.

These and other embodiments are discussed below with reference to FIGS. 1A-7. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these Figures is for explanatory purposes only and should not be construed as limiting.

FIG. 1A shows a perspective view of one example of an electronic device that can include, or be connected, to a charging system. In the illustrated embodiment, the electronic device 100 is implemented as a smart telephone. Other embodiments can implement the electronic device differently, such as, for example, as a laptop or desktop computer, a tablet computing device, a gaming device, a display, a digital music player, a wearable computing device or display such as a watch or glasses, and other types of electronic devices that can receive biometric data from a biometric sensing device.

The electronic device 100 includes an enclosure 102 at least partially surrounding a display 104 and one or more buttons 106 or input devices. The enclosure 102 can form an outer surface or partial outer surface and protective case for the internal components of the electronic device 100, and may at least partially surround the display 104. The enclosure 102 can be formed of one or more components operably connected together, such as a front piece and a back piece. Alternatively, the enclosure 102 can be formed of a single piece operably connected to the display 104.

Electronic device 100 may also include a battery charging port 108. As shown in FIG. 1A, battery charging port 108 may be in electronic communication with battery 110 of electronic device 100. More specifically, battery charging port 108 may including an aperture configured to receive a portion of a charging device 200 (see, FIGS. 2A and 2B) for charging battery 110. That is, battery charging port 108 may be coupled to charging device 200, such that charging device 200 may provide an electric current to electronic device 100 to substantially charge battery 110, as discussed herein.

FIG. 1B is an illustrative block diagram of the electronic device 100 shown in FIG. 1A. The electronic device 100 can include the display 104, a processing device 112, memory 114, an input/output (I/O) device 116, a sensor 118, a network communications interface 120, and a power source 122. The display 104 may display an image or video output for the electronic device 100. The display may also provide an input region for one or more input devices, such as, for example, a touch sensing device and/or a fingerprint sensing device. The display 104 may be substantially any size and may be positioned substantially anywhere on the electronic device 100.

The processing device 112 can control some or all of the operations of the electronic device 100. The processing device 112 can communicate, either directly or indirectly, with substantially all of the components of the electronic device 100. For example, a system bus or signal line 124 or other communication mechanisms can provide communication between the processing device 112, the memory 114, the I/O device 116, the sensor 118, the network communications interface 120, and/or the power source 122. The processing device 112 can be implemented as any electronic device capable of processing, receiving, or transmitting data or instructions. For example, the processing device 112 can be a microprocessor, a central processing unit (CPU), an application-specific integrated circuit (ASIC), a digital signal processor (DSP), or combinations of such devices. As described herein, the term “processing device” is meant to encompass a single processor or processing unit, multiple processors, multiple processing units, or other suitably configured computing element or elements.

The memory 114 can store electronic data that can be used by the electronic device 100. More specifically, in a non-limiting example, memory 114 for electronic device 100 may store electrical data or content relating to the charging of battery 110, as discussed herein. The memory 114 can be configured as any type of memory. By way of example only, the memory can be implemented as random access memory, read-only memory, Flash memory, removable memory, or other types of storage elements, or combinations of such devices.

The electronic device 100 may also include one or more sensors 118 positioned substantially anywhere on the electronic device 100. The sensor(s) 118 may be any conventional sensor for determining an amount of electrical current being provided to electronic device 100, or a sensor configured to determine a time for receiving electrical current during the charging processes discussed herein.

The power source 122 can be implemented with any device capable of providing energy to the electronic device 100. That is, the power source 122 can be one or more disposable batteries or rechargeable batteries (e.g., battery 110) of electronic device 100. More specifically, as shown in FIG. 1B, power source 122 may include battery 110. Additionally, and as discussed in detail herein, power source 122 may include a connection cable or charging device 200 (see, FIGS. 2A and 2B), that may connect electronic device 100, and specifically battery 110, to another power source such as a wall outlet, USB outlet or port or 12V outlet.

The power source 122 may be connected to a battery charging system 126 (hereafter, “charging system 126”). Charging system 126 may be included within electronic device 100, in electronic communication with power source 122 and/or battery 110, or charging system 126 may be included directly within power source 122, as discussed herein. Charging system 126 is generally configured to charge battery 110 of electronic device 100 based on events (e.g., interactions, programs, etc.) that may take place on/with electronic device 100. That is, and as discussed in detail herein, charging system 126 may be configured to charge battery 110 based on anticipated and/or unanticipated events of electronic device 100, and not predetermined charge values of electronic device 100. In one embodiment, the charging system 126 can include a processing device, and a memory. Any suitable processing device and memory can be used in charging system 126. It is understood that other components can be included in charging system 126 in some embodiments. Charging system 126 is described in more detail in conjunction with FIGS. 3-7.

As discussed above, battery 110 of electronic device 100 (see, FIG. 1A) may be charged using charging device 200, as shown in FIGS. 2A-2B. More specifically, as shown in FIG. 2A, charging device 200 may include a connection portion 202 configured to be coupled to electronic device 100 (FIG. 1A), and in electronic communication with battery 110 to provide an electrical current to charge battery 110. Charging device 200 may include a plurality of contact pins 204 positioned on connection portion 202. Contact pins 204 may contact corresponding contact pins (not shown) positioned within battery charging port 108 of electronic device 100 for transferring the electrical current provided by charging device 200 to electronic device 100, to ultimately charge battery 110.

As shown in FIG. 2A, connection portion 202 may be coupled to housing 206 of charging device 200 via insulated wires 208. More specifically, insulated wires 208 may be positioned between connection portion 202 and housing 206 of charging device 200, and may substantially provide an electrical current from housing 206 to connection portion 202 to be subsequently provided to electronic device 100. Housing 206 may be configured to draw an electrical current from any conventional power source. For example, as shown in FIG. 2A, housing 206 may include a two-prong AC power plug 210, which may be configured to be inserted into a conventional wall socket or plug, to draw an electrical current to charging device 200. Although shown as an AC power plug 210, housing 206 and/or charging device 200 may be provided the electrical current from any conventional power supply including but not limited to a USB port or 12V outlet.

As discussed above, charging device 200 may be configured to provide an electrical current to electronic device 100 including charging system 126, to charge battery 110. In an alternative embodiment, charging device 200, as shown in FIG. 2A may include charging system 126, rather than electronic device 100, and charging device 200 may be configured to charge battery 110 using the processes discussed herein with respect to FIG. 3. That is, charging system 126 may be distinct from electronic device 100, and may be included in housing 206 of charging device 200.

Although shown as a single device that may be electrically coupled to electronic device 100, charging device 200 may include an inductive or wireless charging system that may include charging system 126. That is, charging device 200 may be configured as an inductive or wireless charging system including charging system 126, that may be configured to charge battery 110 of electronic device 100 using the processes discussed herein with respect to FIG. 3.

FIG. 2B is an illustrative block diagram of charging device 200 shown in FIG. 2A. The charging device 200 can include a processing device 212, a memory 214, sensors 216, a network communications interface 218, and a power source 220. Charging device 200 may include substantially similar components as those components of electronic device 100 discussed with respect to FIG. 1B. As such redundant explanation of those components may be omitted for clarity.

The processing device 212 can control some or all of the operations of the charging device 200. The processing device 212 can communicate, either directly or indirectly, with substantially all of the components of the charging device 200. For example, a system bus or signal line 222 or other communication mechanisms can provide communication between the processing device 212, the memory 214, sensors 216, the network communications interface 218 and/or the power source 220. The processing device 212 can be implemented as any electronic device capable of processing, receiving, or transmitting data or instructions. For example, the processing device 212 can be a microprocessor, a central processing unit (CPU), an application-specific integrated circuit (ASIC), a digital signal processor (DSP), or combinations of such devices. As described herein, the term “processing device” is meant to encompass a single processor or processing unit, multiple processors, multiple processing units, or other suitably configured computing element or elements.

It should be noted that FIGS. 1A-2B are illustrative only. In other examples, an electronic device and/or charging device may include fewer or more components than those shown in FIGS. 1A-2B.

Turning to FIG. 3, and with continued reference to FIGS. 1A-2B, a process for charging battery 110 of electronic device 100 (FIGS. 1A and 1B) may now be discussed. Specifically, FIG. 3 is a flowchart depicting one sample method 300 for charging battery 110 using charging system 126 of electronic device 100 or charging device 200. That is, the sample method for charging battery 110, as depicted in FIG. 3 and discussed below, may be implemented by charging system 126, regardless of charging system 126 being included within electronic device 100, or charging device 200.

In operation 302, a partially-depleted battery 110 for electronic device 100 may be charged to a threshold charge value. The partially-depleted battery 110 may include any charge value that is below the maximum charge. That is, when the threshold charge value includes a fully charged (e.g., 100%) battery 110, partially-depleted battery 110 may include a charge value less than the maximum charge (e.g., 90-0%). Partially-depleted battery 110 of electronic device 100 may be charged using charging device 200 configured to be electrically coupled to battery charging port 108 of electronic device 100, when charging device 200 may provide electrical currents to electronic device 100. It is understood that the charge of battery 110 may be depleted as a result of a variety of factors including, but not limited to: extended use of electronic device 100; non-charging of electronic device 100; and/or the operational life of battery 110 for electronic device 100.

In operation 304, the charging of battery 110 of electronic device 100 may be discontinued in response to battery 110 being charged to the threshold charge value. That is, when partially-depleted battery 110 of operation 302 is charged to the threshold charge value (e.g., 100%), the electric current provided to electronic device 100 to charge battery 110 may be discontinued. In response to the discontinuing of the charging of battery 110 of electronic device 100, the charge value of battery 110 may gradually deplete. That is, as a result of discontinuing the charge to battery 110, the charge value of battery 110 may deplete or lessen from the threshold charge value over time.

As discussed herein, charging system 126 may recognize that battery 110 has been charged to the threshold charge value, and may subsequently discontinue the charge provided to battery 110 in operation 302. That is, charging system 126 may be in electronic communication with power source 122 including battery 110, and may monitor the charge value of battery 110 to determine when battery 110 is charged to the threshold charge value. When charging system 126 determines that battery 110 is charged to the threshold charge value, charging system 126 may discontinue the charge.

Charging system 126 may discontinue the charge by stopping the electrical current from flowing from charging device 200 (see, FIG. 2A) to electronic device 100. More specifically, charging system 126, in electronic communication with power source 122 and battery 110, may discontinue the draw of electrical current from charging device 200, which may ultimately stop current from flowing to battery 110. In an alternative embodiment, charging system 126 may be in electronic communication with an internal contact pins (not shown) of electronic device 100 and/or contact pins 204 for charging device 200 used for charging battery 110. When battery 110 is charged to the threshold charge value, charging system 126 may temporarily disconnect the contact pins (e.g., contact pins 204), which may ultimately prevent the electrical current provided by charging device 200 to reach electronic device 100 and/or battery 110.

In an alternative embodiment, when charging device 200 includes an inductive or wireless system including charging system 126, the charge to battery 110 of electronic device may also be discontinued in response to battery 110 being charged to the threshold charge value. More specifically, charging system 126 of inductive or wireless system may disconnect or discontinue the transmission of electrical current to battery 110 of electronic device 100, once charging system 126 determines battery 110 is charged to the threshold charge value.

As such, the discontinuing of the charge to battery 110 in operation 304 may also include maintaining the electrical coupling between the charging device 200 and battery 110 of electronic device 100. That is, as a result of charging system 126 controlling and/or discontinuing the charge provided to battery 110, the charging device 200 may remain substantially coupled to battery charging port 108 and may remain electrically coupled to battery 110. As discussed herein, by maintaining the electrical coupling between the charging device 200 and battery 110 of electronic device 100, charging system 126 may reactivate or recharge battery 110.

In operation 306, a function of electronic device 100 may be monitored to detect an anticipated event and/or an unanticipated event of electronic device 100. That is, charging system 126 may monitor the function, operation and/or interactions of electronic device 100, when electrically coupled to the charging device 200, to detect anticipated and/or unanticipated events that may take place on or with respect to electronic device 100.

The anticipated events of electronic device 100 detected during the monitoring process in operation 306 may include a predetermined operation of electronic device 100, and/or a reoccurring interaction with electronic device 100.

For example, a predetermined operation of electronic device 100 may be a scheduled alarm set on electronic device 100. More specifically, electronic device 100 may be configured to include a programmable alarm that may alert a user of electronic device 100 at a predetermined time.

A reoccurring interaction with electronic device 100 may be a learned and/or regular interaction a user may have with electronic device 100. In an example, the reoccurring interaction with electronic device 100 may include a substantially consistent, and regular times for coupling and uncoupling charging device 200 to electronic device 100. That is, the reoccurring interaction with electronic device 100 may be learned by charging system 126 when a user regularly couples electronic device 100 to the charging device 200 at a first time, and uncouples the electronic device 100 from the charging device 200 at a second time.

The unanticipated events of electronic device 100 detected during the monitoring process in operation 306 may include a spontaneous, unexpected interaction with electronic device 100. As one example, an unanticipated event of electronic device 100 may include a user randomly interacting with electronic device 100 when electronic device 100 is electrically coupled to the charging device 200. For example, when a user electrically couples electronic device 100 to the charging device 200 while the user sleeps, an unanticipated event may include the user unexpectedly checking the time using electronic device 100 after randomly waking-up.

In operation 308, battery 110 of electronic device 100 may be recharged in response to detecting one of an anticipated event and/or an unanticipated event. More specifically, charging system 126 may reactivate or continue the charging of battery 110 in response to detecting an anticipated event and/or an unanticipated event during the monitoring of the function of electronic device during operation 306. The detected anticipated event may occur a predetermined time subsequent to the recharging of battery 110. That is, and as discussed herein, the recharging of battery 110 may begin a predetermined time before the detected, anticipated event is expected to occur. Additionally, the detected unanticipated event may occur immediately before the recharging of battery 110 of operation 308. More specifically, and discussed herein, the recharging of battery 110 may begin immediately after the detected, unanticipated event occurs.

When an anticipated event is detected or predicted in operation 306, the recharging of battery 110 in operation 308 may include charging battery 110 to the threshold charge value (e.g., 100% charge) prior to the occurrence of the anticipated event. That is, when an anticipated event is expected to occur on electronic device 100, charging system 126 may begin to charge battery 110 a predetermined time prior to the expected occurrence of the anticipated event to ensure battery 110 is charged to the threshold charge value prior to the occurrence of the anticipated event. Additionally, when an anticipated event is detected in operation 306, the recharging of battery 110 in operation 308 may include charging battery 110 at a first rate prior to the occurrence of the anticipated event. That is, charging system 126 may be configured to provide battery 110 a charge within a plurality of distinct charging rates, including a first charging rate, which may be used to charge battery 110 when an anticipated event is detected. As such, during the recharging of battery 110 of electronic device 100 in operation 308, charging system 126 may begin to charge battery 110 at a first rate, a predetermined time prior to the expected occurrence of the anticipated event. As can be understood, the predetermined time to begin recharging battery 110 of electronic device 100 can be determined based on a variety of operational functions of electronic device 100 and/or charging system 126 including, but not limited to: the charging rate used to charge battery 110, and the charge value of partially depleted battery 110 (e.g., operation 304).

When an unanticipated event is detected in operation 306, the recharging of battery 110 in operation 308 may include charging battery 110 to the threshold charge value (e.g., 100% charge) or to a nearly threshold charge value, subsequent to the occurrence of the unanticipated event. That is, when the unanticipated event is detected on electronic device 100, battery 110 may be charged to the threshold charge value, or as close to the threshold charge value as possible after the unanticipated event occurs, but prior to the disconnection between electronic device 100 and the charging device 200. Additionally, in detecting the unanticipated event in operation 306, the recharging of battery 110 in operation 308 may include charging battery 110 at a second rate, distinct from the first rate, immediately after the occurrence of the unanticipated event. As discussed above, charging system 126 may be configured to provide battery 110 a charge with a plurality of distinct charging rates. As such, when the unanticipated event is detected, charging system 126 may charge battery 110 at a second rate, distinct (e.g., greater) from the first rate, to charge battery 110 to the threshold charge value, or as close to the threshold charge value as possible.

Although depicted in FIG. 3 and discussed herein as occurring subsequent to the charging in operation 302, and the discontinuing of the charge in operation 304, the monitoring of the function of electronic device 100 in operation 306 can occur prior to, or simultaneous to, operation 302 and/or operation 304. That is, the monitoring in operation 306 may occur prior to the charging in operation 302 and/or the discontinuing of the charge in operation 304. Additionally, the monitoring in operation 306 may occur concurrently with the charging in operation 302 and/or the discontinuing of the charge in operation 304. As such, it is understood that the monitoring of operation 306 may occur any time between the electrical coupling of charging device 200 and electronic device 100, the recharging of battery 110 in operation 308.

FIG. 4 shows an illustrative linear graph representing the method of charging battery 110 for electronic device 100, as depicted in FIG. 3. An example of charging battery 110 of electronic device 100 using the method depicted in FIG. 3 may now be discussed with respect to FIG. 4.

As shown in FIG. 4, the linear graph may represent the charge value of battery 110 over a period of time. More specifically, the linear graph may represent the charge value of battery 110 in electronic communication with charging system 126, when the charge value of battery 110 is determined and/or modified by charging system 126, of the system discussed herein. In the example embodiment, as shown in FIG. 4 and discussed herein, an anticipated event may be detected by charging system 126.

Charging system 126 may determine that electronic device 100 may be electrically coupled to the charging device 200 at initial time T₀ to charge battery 110. As shown in FIG. 4, at initial time T₀, charging system 126 may determine that battery 110 may be partially-depleted to include an initial charge value (CV₀) less than the threshold charge value for battery 110. The initial charge value (CV₀) may be any charge value that is less than the threshold charge value for battery 110. As discussed herein, the threshold charge value may be any predetermined charge value for battery 110 of electronic device 100. In a non-limiting example, as shown in FIG. 4, threshold charge value may include a maximum charge value (CV_(MAX)) (e.g., 100%) for battery 110. As a result of determining battery 110 includes an initial charge value (CV₀) less than the threshold charge value (CV_(MAX)), charging system 126 may begin to charge battery 110. More specifically, as shown in FIG. 4, charging system 126 may begin to charge battery 110 over a period of time, such that battery 110 may eventually include a charge value equal to the threshold charge value (CV_(MAX)). As shown in FIG. 4, battery 110 may be charged to include the threshold charge value (CV_(MAX)) at a charge time T₁. The charging of battery 110 between the electrical coupling at initial time T₀ and threshold charge value of battery 110 at the charge time T₁ may corresponding to the charging in operation 302 of FIG. 3.

It is understood, that the threshold charge value may include any predetermined charge value for battery 110 of electronic device 100. More specifically, the threshold charge value may include a predetermined charge value for battery 110 that is less than the maximum charge value (CV_(MAX)), as shown in FIG. 4. In a non-limiting example, the threshold charge value for battery 110 may include a 90% charge. That is, and as similarly discussed herein, it may be determined that battery 110 includes an initial charge value (CV₀) less than the threshold charge value of 90% of the charge of battery 110. As a result, charging system 126 may begin to charge battery 110 to eventually include a charge value equal to the threshold charge value (e.g., 90%).

As shown in FIG. 4, charging system 126 may charge battery 110 at a second charge rate (ΔCR₂), which may be greater than a first charge rate (ΔCR₁), as discussed herein. Charging system 126 may initially charge battery 110 at the increased, second charge rate (ΔCR₂) between time T₀ and T₁ to achieve the threshold charge value (CV_(MAX)) for battery 110 as quickly as possible. When battery 110 is being charged at the second charge rate (ΔCR₂), charging system 126 may be instructing or requesting the maximum amount of electrical current capable of being provided to electronic device 100 and/or capable of being drawn by charging device 200.

As shown in FIG. 4, once battery 110 reaches the threshold charge value (CV_(MAX)) at the charge time T₁, charging system 126 may allow the charge value (CV) of battery 110 to gradually deplete. That is, between charge time T₁ and charge time T₂, the charge value for battery 110 of electronic device may gradually deplete from the threshold charge value (CV_(MAX)). The gradual depletion of the charge value of battery 110 of electronic device 100 may be a result of charging system 126 discontinuing the charge of battery 110 in response to battery 110 being charged to the threshold charge value (CV_(MAX)) at charge time T₁. The discontinuing of the charge to battery 110, and the depletion of the charge value between charge time T₁ and charge time T₂, as shown in FIG. 4, may corresponded to operation 304 in FIG. 3.

As discussed herein, the discontinuing of the charge to battery 110 may be controlled by charging system 126 while substantially maintaining the electrical coupling between the charging device 200 and battery 110 of electronic device 100. In maintaining the electrical coupling between charging device 200 and battery 110 of electronic device, charging system 126 may be able to reinitiate the charging of battery 110 at any time during the charging process. That is, when charging device 200 remains electrically coupled to and in electronic communication with battery 110 of electronic device 100, charging system 126 may discontinue and/or recharge battery 110 immediately after the detection of an event (e.g., unanticipated event) that may require battery 110 to be charged to the threshold charge value (CV_(MAX)) instantaneously.

At charge time T₂, charging system 126 may determine that battery 110 includes a predetermined, partial charge value CV_(PRE). That is, charging system 126 may continuously monitor the charge value (CV) of battery 110 after discontinuing the charge at charge time T₁, to identify when the charge value (CV) for battery 110 equals the predetermined, partial charge value (CV_(PRE)) at charge time T₂. When battery 110 includes the predetermined, partial charge value (CV_(PRE)), charging system 126 may be configured to maintain battery 110 at predetermined, partial charge value (CV_(PRE)). That is, subsequent to the discontinuing of the charge, and the resulting depletion of the charge value (CV) for battery 110, charging system 126 may be configured to detect and substantially maintain battery 110 at the predetermined, partial charge value (CV_(PRE)). Charging system 126 may substantially maintain the predetermined, partial charge value (CV_(PRE)) for battery 110 between second charge time T₂ and charge time T₃. More specifically, as shown in FIG. 4, between charge time T₂ and charge time T₃, charging system 126 may allow the charging device 200 to provide a temporary, partial-charge to battery 110, when the partial-charge substantially maintains the predetermined, partial charge value (CV_(PRE)) for battery 110. That is, the partial-charge provided to battery 110 between charge time T₂ and charge time T₃ may substantially maintain the predetermined, partial charge value (CV_(PRE)) and may not substantially fluctuate from the predetermined, partial charge value (CV_(PRE)).

Briefly turning to FIG. 5, an alternative embodiment for maintain the predetermined, partial charge value (CV_(PRE)) may be shown. Specifically, as shown in FIG. 5, between charge time T₂ and charge time T₃, charging system 126 may maintain an average predetermined, partial charge value (CV_(PRE)) for battery 110 by fluctuating the charge value of battery 110 between a maximum predetermined, partial charge value (CV_(PREMAX)), and a minimum predetermined, partial charge value (CV_(PREMIN)). As shown in FIG. 5, both the maximum predetermined, partial charge value (CV_(PREMAX)), and minimum predetermined, partial charge value (CV_(PREMIN)) may be substantially below the threshold charge value (CV_(MAX)) for battery 110, to substantially prevent negatively effecting the life of battery 110, as discussed herein. Charging system 126 may fluctuate the charge value (CV) for battery 110 between the maximum predetermined, partial charge value (CV_(PREMAX)), and minimum predetermined, partial charge value (CV_(PREMIN)) by repeatedly charging and discontinuing the charging of battery 110, as discussed herein.

As discussed herein, the predetermined, partial charge value (CV_(PRE)) for battery 110 of electronic device 100 may be dependent upon the charge rate (e.g., first charge rate, second charge rate) applied by charging system 126 for recharging battery 110. More specifically, and as discussed herein, dependent upon the detection of an anticipated event and/or an unanticipated event, and the corresponding charge rate associated with the respective events, charging system 126 may adjust the charge value (CV) for the predetermined, partial charge value (CV_(PRE)) for battery 110.

Returning to FIG. 4, at any time between the initial time T₀ of electrically coupling battery 110 of electronic device 100 to charging system 126 and charge time T₃ may the charging system 126 monitor the functions of electronic device 100 to detect the anticipated event (Event_(ANTCP)). That is, and as discussed herein, charging system 126 may monitor the functions of electronic device 100 prior to, during, or subsequent to the charging of battery 110 (e.g., T₀-T₁), the discontinuing of the charge to battery 110 (e.g., T₁-T₂) and/or the maintaining of the predetermined, partial charge value (CV_(PRE)) of battery 110 (e.g., T₂-T₃) to detect the anticipated event (Event_(ANTCP)).

As shown in FIG. 4, charging system 126 may monitor the function of electronic device 100 to detect the anticipated event (Event_(ANTCP)) is expected to occur at charge time T₄. That is, charging system 126 may interact with other components of electronic device 100 (e.g., memory 114, processing device, etc.) to determine that electronic device 100 has an anticipated event (Event_(ANTCP)) that may be expected to occur at charge time T₄. In a non-limiting example, the anticipated event (Event_(ANTCP)) occurring at charge time T₄ may include an alarm of electronic device 100 scheduled for charge time T₄. the monitoring to detect anticipated event (Event_(ANTCP)) at charge time T₄ may correspond to operation 306 in FIG. 3.

As shown in FIG. 4, between charge time T₃ and charge time T₄ battery 110 may be recharged to the threshold charge value (CV_(MAX)). More specifically, charging system 126 may allow the charging device 200 to recharge battery 110 at a first charging rate (ΔCR₁) to the threshold charge value (CV_(MAX)) prior to the occurrence of the anticipated event (Event_(ANTCP)) at charge time T₄. By charging battery 110 at first charging rate (ΔCR₁), rather than the increased, second charging rate (ΔCR₂), battery 110 may be charged to threshold charge value (CV_(MAX)) using less electrical current. That is, when charging system 126 detects anticipated event (Event_(ANTCP)), and may recharge battery 110 to threshold charge value (CV_(MAX)) over a predetermined time, as discussed below, charging system 126 may charge battery 110 at first charging rate (ΔCR₁).

Because first charging rate (ΔCR₁) requires less electrical current from charging device 200, the charging of battery 110 may reduce the home-electrical cost of charging battery 110, and/or may also allow battery 110 to be charged with an electrical current below the maximum allowed current for electronic device 100. This may ultimately, provide less electrical stress to battery 110 and/or electronic device 100 during the charging process discussed herein. The recharging of the battery 110 between the third charge time T3 and the fourth charge time T4 may correspond to operation 308 in FIG. 3.

As shown in FIG. 4, and discussed herein, the time between charge time T₃ and charge time T₄ may be the predetermined time for charging battery 110, which may be dependent upon the anticipated event, the predetermined, partial charge value (CV_(PRE)) and/or the rate of charging battery 110 prior to the anticipated event (Event_(ANTCP)). That is, charging system 126 may determine that the charging device 200 may begin charging battery 110 at charge time T₃, as a result of battery 110 being charged at the first charge rate and/or the anticipated event (Event_(ANTCP)) expected to occur at charge time T₄.

As shown in FIG. 4, by determining and beginning the recharging of battery 110 at charge time T₃, charging system 126 may ensure that battery 110 is charged and maintained at the threshold charge value (CV_(MAX)) prior to the anticipated event (Event_(ANTCP)). As a result, when the anticipated event (Event_(ANTCP)) occurs, and electronic device 100 is immediately uncoupled from the charging device 200 at charge time T₄, the battery 110 of electronic device 100 may include the threshold charge value (CV_(MAX)), and may only have reached the threshold charge value (CV_(MAX)) twice during the charging process performed by charging system 126 (e.g., T₀-T₄).

Turning to FIG. 6, a linear graph, according to an alternative embodiment, may represent the charge value of battery 110 in electronic communication with charging system 126, when the charge value of battery 110 is determined and/or modified by charging system 126, of the system discussed herein. In the embodiment, as shown in FIG. 6 and discussed herein, an unanticipated event (Event_(UNANTCP)) may be detected by charging system 126.

As shown in FIG. 6, the linear graph representing the charge value for battery 110 of electronic device 100 may function and/or may undergo processes by charging system 126 similar to those discussed in FIG. 4. That is, the linear graph illustrated in FIG. 6 may be substantially identical to the linear graph in FIG. 4 between the initial time T₀ and charge time T₂. The similarity may be a result of charging system 126 performing substantially similar, initial processes (e.g., charging, discontinuing the charging, etc.) with respect to an anticipated event (Event_(ANTCP)) (see, FIG. 4) and an unanticipated event (Event_(UNANTCP)) (FIG. 6). As such, redundant explanation of the charge value for battery 110, as shown in FIG. 6 between the initial time T₀ and charge time T₂ is omitted for clarity.

However, and in comparison to FIG. 4, after charge time T₂, and specifically, during the maintaining of the predetermined, partial charge value (CV_(PRE)) of battery 110, the unanticipated event (Event_(UNANTCP)) may be detected by charging system 126. More specifically, charging system 126 may continuously monitor the function of electronic device 100, and ultimately may detect the occurrence of the unanticipated event (Event_(UNANTCP)) at charge time T₅. As discussed herein, the unanticipated event (Event_(UNANTCP)) may include a spontaneous or unexpected interaction with electronic device 100 while electronic device is undergoing the charging processes discussed herein with respect to FIG. 3. In a non-limiting example, the unanticipated event (Event_(UNANTCP)), as shown in FIG. 6, may include a user unexpectedly checking the time using electronic device 100 after randomly waking up in the middle of the night.

As shown in FIG. 6, once the unanticipated event (Event_(UNANTCP)) is detected, charging system 126 may begin the recharging of battery 110. That is, immediately subsequent to the detection and/or occurrence of the unanticipated event (Event_(UNANTCP)) at charge time T₅, charging system 126 may allow the charging device to provide current to battery 110 at charge time T₆ to recharge battery 110 to the threshold charge value (CV_(MAX)), or close to the threshold charge value (CV_(MAX)).

Charging system 126 may allow battery 110 to be charged at the second charge rate (ΔCR₂), which may be greater than the first charge rate (ΔCR₁) (see, FIG. 4). More specifically, charging system 126 may allow battery 110 to be charged at the second charge rate (ΔCR₂) so battery 110 may be charged to the threshold charge value (CV_(MAX)) or as close to it as possible, over, for example, the shortest possible duration of time. That is, because of the spontaneity of unanticipated event (Event_(UNANTCP)), and/or the inability of charging system 126 to detect the unanticipated event (Event_(UNANTCP)) until after the event occurs, it may not be determined how long electronic device 100 will remain electrically coupled to charging device after the occurrence unanticipated event (Event_(UNANTCP)). As such, charging system 126 may charge battery 110 at the greater, second charge rate (ΔCR₂), in order for battery 110 to include a greater charge value prior to the uncoupling of electronic device 100 and charging device 200.

As shown in FIG. 6, battery 110 may be charged at the second charge rate (ΔCR₂) between charge time T₆ and charge time T₇, where at charge time T₇, electronic device 100 may be uncoupled from charging device 200. As a result of uncoupling electronic device 100 from charging device 200 at charge time T₇, battery 110 may not be completely charged to the threshold charge value (CV_(MAX)), but may only be charged to a nearly threshold charge value (CV_(NEAR)). However, as shown in phantom in FIG. 6, if electronic device 100 remained electrically coupled to charging device 200 until charge time T₄, battery 110 may be charged to the threshold charge value (CV_(MAX)), as similarly discussed with respect to FIG. 4.

In an additional embodiment, charging system 126 may detect both an anticipated event (Event_(ANTCP)) and an unanticipated event (Event_(UNANTCP)) while battery 110 is in electronic communication within charging system 126. That is, as shown in FIG. 7, which battery 110 of electronic device 100 is in electronic communication with charging system 126, both an anticipated event (Event_(ANTCP)) and an unanticipated event (Event_(UNANTCP)) may be detected by charging system 126. When both an anticipated event (Event_(ANTCP)) and an unanticipated event (Event_(UNANTCP)) are detected by charging system 126, the predetermined, partial charge value (CV_(PRE)) substantially maintained by charging system 126 may vary.

In the example embodiment shown in FIG. 7, a non-limiting example of an anticipated event (Event_(ANTCP)) may include an alarm on electronic device 100, as discussed above with respect to FIG. 4. Additionally, a non-limiting example of an unanticipated event (Event_(UNANTCP)) may include a user unexpectedly checking the time using electronic device while battery 110 is in electronic communication with charging system 126, as discussed above with respect to FIG. 6.

The linear graph representing the charge value for battery 110 of electronic device 100 in FIG. 7 may function and/or may undergo processes by charging system 126 similar to those discussed in FIGS. 4 and/or 6. More specifically, as discussed above with respect to FIGS. 4 and/or 6, battery 110 may be electrically coupled with charging system 126 at initial time T₀, and may be charged to the threshold charge value (CV_(MAX)) between initial time T₀ and charge time T₁. Additionally, as similarly discussed with respect to FIG. 4, charging system 126 may detect the anticipated event (Event_(ANTCP)) at charge time T₄ by monitoring the function of electronic device 100. Finally, and as similarly discussed with respect to FIG. 6, charging system 126 may detect the unanticipated event (Event_(UNANTCP)) at charge time T₅ and may immediately allow battery 110 to be recharged at the second charge rate (ΔCR2) at charge time T₆.

As shown in FIG. 7, between charge time T₅ and charge time T₆, charging system 126 may maintain battery 110 at a first predetermined, partial charge value (CV_(PRE1)).The first predetermined, partial charge value (CV_(PRE1)) may be substantially equal to a predetermined, partial charge value (CV_(PRE)) determined by charging system 126, when an anticipated event (Event_(ANTCP)) is detected (see, FIG. 4). That is, and as discussed herein, when an anticipated event (Event_(ANTCP)) is detected by charging system 126 at charge time T₄, charging system 126 may allow battery 110 to deplete to first predetermined, partial charge value (CV_(PRE1)) at charge time T₂, and may substantially maintain first predetermined, partial charge value (CV_(PRE1)) until a time when recharging of battery 110 is required (e.g., T₄, T₆), as discussed herein.

As similarly discussed herein with respect to FIG. 6, charging system 126 may allow charging device 200 to begin charging battery 110 to the threshold charge value (CV_(MAX)) at charge time T₆. As shown in FIG. 7, battery 110 may be charged to the threshold charge value (CV_(MAX)) at charge time T₈ and may be subsequently maintained at the threshold charge value (CV_(MAX)). Battery 110 may be maintained at the threshold charge value (CV_(MAX)) in anticipation of battery 110 of electronic device 100 being uncoupled from charging device 200 by user. However, if battery 110 remains in electronic communication with charging device 200 for a predetermined time, charging system 126 may again discontinue the charge to battery 110 and may allow the charge value of battery 110 to begin to deplete. The predetermined time may be indicated by the time between charge time T₈ and charge time T₉, where at charge time T₉, charging system 126 may discontinue the charge supplied to battery 110 by charging device 200, and may allow the charge value (CV) of battery 110 to deplete, as similarly discussed with respect to FIG. 4 between charge time T₁ and charge time T₂.

Charging system 126 may allow charging value (CV) to deplete until charge time T₁₀, when the charge value (CV) for battery 110 is equal to a second predetermined, partial charge value (CV_(PRE2)). As shown in FIG. 7, the second predetermined, partial charge value (CV_(PRE2)) for battery 110 may be substantially greater than the first predetermined, partial charge value (CV_(PRE1)) between charge time T₂ and T₅. Charging system 126 may adjust the predetermined, partial charge value (CV_(PRE)) for battery 110 in response to the detecting of the unanticipated event (Event_(UNANTCP)) at charge time T₅. That is, and as discussed herein, the predetermined, partial charge value (CV_(PRE)) for battery 110 may be dependent upon, at least in part, the charge rate (ΔCR) for recharging battery 110 and/or the detection of an anticipated event (Event_(ANTCP)) and/or an unanticipated event (Event_(UNANTCP)) by charging system 126. As such, and as shown in FIG. 7, first predetermined, partial charge value (CV_(PRE1)) determined by charging system 126 may be dependent on the detection of the anticipated event (Event_(ANTCP)) expected to occur at charge time T₄. However, the detection and/or the occurrence of unanticipated event (Event_(UNANTCP)) at charge time T₅ by charging system 126 may result in charging system 126 to adjust the predetermined, partial charge value (CV_(PRE)) to second predetermined, partial charge value (CV_(PRE2)). Charging system 126 may adjust to second predetermined, partial charge value (CV_(PRE2)) to relatively ensure that subsequent recharging processes performed on battery 110 may result in battery 110 including the threshold charge value (CV_(MAX)) before the anticipated event (Event_(ANTCP)) occurs and/or battery 110 is uncoupled from charging device 200. That is, by maintaining battery 110 at second predetermined, partial charge value (CV_(PRE2)), which may be greater than the first predetermined, partial charge value (CV_(PRE1)), battery 110 may be more quickly charged to the threshold charge value (CV_(MAX)) when another unanticipated event (Event_(UNANTCP)) occurs, and/or before an anticipated event (Event_(ANTCP)) occurs.

The second predetermined, partial charge value (CV_(PRE2)) for battery 110 may be substantially maintained by charging system 126 between charge time T₁₀ and T₁₁, as similar discussed herein with respect to FIG. 4 between charge time T₂ and charge time T₃. That is, charging system 126 may maintain second predetermined, partial charge value (CV_(PRE2)) for battery 110, without the detection of a distinct unanticipated event (Event_(UNANTCP)). As similarly discussed herein with respect to FIG. 4 between charge time T₃ and T₄, charging system 126 may allow charging device 200 to recharge battery 110 at charge time T₁₁. More specifically, at charge time T₁₁, charging system 126 may begin to charge battery 110 at a first charge rate (ΔCR₁) to the threshold charge value (CV_(MAX)), and may substantially maintain battery 110 at the threshold charge value (CV_(MAX)) prior to the occurrence of the anticipated event (Event_(ANTCP)) at charge time T₄. As similarly discussed herein with respect to FIG. 4, the time duration between charge time T₁₁ and T₄ may represent the predetermined time for recharging battery 110 to ensure battery 110 will include the threshold charge value (CV_(MAX)) prior to the occurrence of the anticipated event (Event_(ANTCP)).

By utilizing charging system 126 to charge battery 110 of electronic device 100, the charging of battery 110 may be dependent upon the monitoring and/or the occurrence of events (e.g., anticipated, unanticipated) of electronic device 100, and not cycling between threshold charge values and minimum charge values. As a result, charging system 126 utilized by electronic device 100 may substantially prevent undesirable depletion of battery's 110 ability to maintain a charge. That is, by eliminating the cycling charging of battery 110 of electronic device 100, charging system 126 utilized by electronic device 100 may minimize and substantially prevent the depletion of battery's 110 ability to maintain a charge.
